SPRING-PRESS.

Application filed October 25, 1915.

To all whom it may concern:

Be it known that I, GIUSEPPE VInoLI, a citizen of the United States, residing at Reno, in the county of Washoe and State of Nevada, have invented new and useful Improvements in; Spring-Presses, of which the following is a specification.

This invention relates to a spring press.

One of the objects of the present invention is to provide a simple, substantial,

easily operated press for forming or bending the several leaves of which a standard elliptical spring is constructed and to provide means by which the several leaves in a set may be formed in one operation.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure l is a side elevation of the press. Fig. 2 is an end View of same. Fig. 3 is a sectional view of the spring leaf holder taken on line 3-3 of Fig. 5. F ig. 4 is an end view of same. Fig.5 is a bottom view of the holder, showing the spring leaves in position.

Referring to the drawings in detail, A indicates a frame of suitable size and construction upon which is mounted a stationary forming die or anvil 2. Mounted above the die 2 in direct alfinement with same and guided by means of a pair of rods 3 which pass through a pair of bearings 4,

carried by the upper end of the frame, is a hammer or movable die 5, which is raised and lowered with relation to the anvil 2, by means of a lever 6 which is pivotally mounted, as at 7, uponthe frame. This lever is connected with the hammer 5 by means of a link 8 and the lever may be locked in its raised position by means of a pawl 9,

which is operated by suitable means, such as the rod 10. Adapted to be raised and lowered with relation to the anvil '2 by means of a lever 11, is a platform 12 upon which .are secured three pairs of guide rods, such as indicated at 13, la and 15. These rods extend through the base plate 16 upon which the anvil is mounted and in a position where they will embrace the leaf springs and hold same in alinement with the forming die; the platform carrying the guide rods may be locked or supported in Specification of Letters Patent.

its raised position by means of the pawl andratchet, indicated at 17.

placed between the forming dies or the hammer and anvilm the press, and are here subjected to pressure of the blow of the hammer, to producevthe desired shape or curvature.

The holder proper consists of a forkto permit it to be conveniently handled. One of the legs of the fork-shaped frame is pivotally mounted, as at 20, while the other leg 21 is rigid and stationary. Suspended from the center portion of the fork-shaped frame or the upper bar of same by means of rods 22, is a plurality of intermediate spacing and forming dies 23, and passing through the pivotally mounted rods 22 upon which the intermediate forming dies 23 are secured, is a pair of horizontally disposed rods 24, which are operated in unison to either clamp or release the spring leaves 25 placed between the intermediate spacing dies by means of arlever 26. After the several leaves or blanks 25 have been brought to the desired temperature it is necessary to insert the leaves between the intermediate are furthermore separated by coil-springs 27 which are carried by the rods 24 and interposed between each set of suspension rods 22. After the intermediate dies have been separated by the operation, as described, it is then possible. to insert the leaves or blanks 25 between the dies, as indicated in Figs. 3 and 5. The lever 26 is then brought back to the full-line position shown, and this movement of the lever pulls the rods 21 in the direction of arrow in and causes sufiicient compression of the springs 27 to bring the intermediate dies together and clamp the blanks between same.

The holder as a unit containing the leaf blanks is then placed on the anvil 2; the platform 12 is then'raised into a position where the guide rods 13 will straddle the shaped frame 18 provided with a handle 19 shape being determined bythe shape of the anvil and hammer, and also by the inter-' mediate spacing dies 23. o The dies are retained in the depressed position by means of a weight 30 ,andthe lever may remain in thi'sposition until the several leaves of the 5 spring have cooled sufliciently to retain the shape or permanent set required- I It-will be observed that during the descent of the die 5, it first acts upon the outer 1 ends of, the long blanks and then successively '1 and quickly upon the ends of the shorter blanks. The pressure applied or power re- 7 quired is thus gradually transmitted, as each 1 leaf is bent to 'setin successive order.

the time required is greatly decreased by the o holder 18 and release theseveral leaves by moving the lever 26 into the dottedline position, shown... The .same cycle of; opera- The provision of the intermediate spacing dies 23 permits each leaf to be bent to as- I sume a different curvature and it also permits all the leaves comprising a set to be formed in one operation. A uniform prodact is furthermore produced and a great saving in cost of manufacture 1s secured, as

present operation.

After the leaves have been set or given their proper respective curvature, it is only necessary to raise the hammer 5, remove-the tion takes place with each set of springs and any suitable form oftongs may be provided for the purpose of placing the leaves in the,

holder and as this forms no part of the present invention, no means have been illustrated.

n The materlals and finish of the several.

partsof the device may be such as the 'judgment and experience of the manufacturer may dictate.

I wish it understood that various'changes in form, proportions and'minor detailsof construction may, be resorted to within the. V

scope of theappended claims and that I do not wish to limit myself to the specific de- ,7

sign and construction here shown.
